Are there any reports of white teenagers doing this?
When I was living in New Hampshire there was a big case in Cambridge, MA where 2 white kids playing the knockout game (that's even what they called it in the paper) ended up killing an MIT student. The one kid who did the punching showed up for his hearing with a broken hand. That was in the early 1990's.
When I was in high school (now we're talking 1970's)one of our teachers talked about how when he was growing up in Jersey City he and his friends used to pile into a car, draw cards and in order pick a street, let one person out and he would have to fight the first man who walked by. That would have been in the 1950's.
This first became popular in the 70’s.
I’ve had it done to me twice.
Both time it was by a white punk that had just got out of the pen.
Both time they found out this head is a lot harder than they thought.
Both found out what happens when you loose the “Knockout Game” and your “victim” wins the “Knockout Game”.
One got his feelings, and face, hurt so bad he decided to go steal a crate of oranges to break his parole so he could go back to the pen where it was safe.
